The article conveys some information:

One of the hallmarks of cancer is chromosome instability (CIN), which leads to aneuploidy, translocations, and other chromosome aberrations. However, in the vast majority of human tumors the mol. basis of CIN remains unknown, partly because not all genes controlling chromosome transmission have yet been identified. To address this question, we developed an exptl. high-throughput imaging (HTI) siRNA assay that allows the identification of novel CIN genes. Our method uses a human artificial chromosome (HAC) expressing the GFP transgene. When this assay was applied to screen an siRNA library of protein kinases, we identified PINK1, TRIO, IRAK1, PNCK, and TAOK1 as potential novel genes whose knockdown induces various mitotic abnormalities and results in chromosome loss. The HAC-based assay can be applied for screening different siRNA libraries (cell cycle regulation, DNA damage response, epigenetics, and transcription factors) to identify addnl. genes involved in CIN. Identification of the complete spectrum of CIN genes will reveal new insights into mechanisms of chromosome segregation and may expedite the development of novel therapeutic strategies to target the CIN phenotype in cancer cells.

The article was titled 《Development of 1,3-thiazole analogues of imidazopyridines as potent positive allosteric modulators of GABAA receptors》, and you may find the article in Bioorganic Chemistry.Recommanded Product: 6-Chlorobenzothiazol-2-ylamine The information in the text is summarized as follows:

Structure-activity relationship studies were conducted in the search for 1,3-thiazole isosteric analogs of imidazopyridine drugs (Zolpidem, Alpidem). Three series of novel γ-aminobutyric acid receptor (GABAAR) ligands belonging to imidazo[2,1-b]thiazoles I [R1 = OMe, NMe2, OEt; R2 = p-chlorophenyl], [R1 = OMe, R2 = p-nitrophenyl] and [R1 = OEt, R2 = o,p-dichlorophenyl], imidazo[2,1-b][1,3,4]thiadiazoles II [R3 = OEt, NMe2, NPr2; R4 = p-chlorophenyl; R5 = Et, iso-Pr, MOM] and benzo[d]imidazo[2,1-b]thiazoles III [R6 = NH2, OEt, NMe2, NEt2, NPr2; R7 = Ph, p-fluorophenyl o,p-dimethoxyphenyl, etc.; R8 = H, Cl, OMe] were synthesized and characterized as active agents against GABAAR benzodiazepine-binding site. In each of these series, potent compounds were discovered using a radioligand competition binding assay. The functional properties of highest-affinity compounds III [R6 = NH2, R7 = p-chlorophenyl, R8 = H] and [R6 = NMe2, R7 = o-chlorophenyl, R8 = H] as GABAAR pos. allosteric modulators (PAMs) were determined by electrophysiol. measurements. In-vivo studies on zebrafish demonstrated their potential for the further development of anxiolytics. Using the OECD “”Fish, Acute Toxicity Test”” active compounds were found safe and non-toxic. Structural bases for activity of benzo[d]imidazo[2,1-b]thiazoles were proposed using mol. docking studies. The isosteric replacement of the pyridine nuclei by 1,3-thiazole, 1,3,4-thiadiazole, or 1,3-benzothiazole in the ring-fused imidazole class of GABAAR PAMs was showed to be promising for the development of novel hypnotics, anxiolytics, anticonvulsants and sedatives drug-candidates.6-Chlorobenzothiazol-2-ylamine(cas: 95-24-9Recommanded Product: 6-Chlorobenzothiazol-2-ylamine) was used in this study.

The synthesized hydroxypyrazolones were assayed for their anticancer activity against two human cancer cell lines (i) lung carcinoma (A549) and (ii) breast carcinoma (MCF7) using MTT assay. Among all the tested compounds, I (R1 = Me; R2 = Cl) and I (R1 = Br; R2 = H) with IC50 values in the range of 30.68 +/- 0.57μM to 34.87 +/- 0.76μM exhibited moderate inhibitory ability against both the tested cancer cell lines in comparison to the standard drug Doxorubicin (0.95 +/- 0.10μM for A549 and 1.09 +/- 0.11μM for MCF7). The above two compounds were further tested against normal human embryonic kidney cell line (HEK 293T) to examine their toxicity against normal cell lines. Selectivity Index (S.I.) of these compounds was calculated for both the cancer cell lines which revealed that these derivatives i.e. I (R1 = Me; R2 = Cl) (S.I = 2.82 for A549 and 2.90 for MCF7) and I (R1 = Br; R2 = H) (S.I = 2.78 for A549 and 2.95 for MCF7) are safer anticancer agents.

The article was written by Harisha, S.; Keshavayya, Jathi; Prasanna, S. M.; Joy Hoskeri, H.. The article contains the following contents:

A series of novel benzothiazole based azo dyes were synthesized and fully characterized by using different anal. techniques. The antioxidant activity of synthesized azo dyes was studied with the DPPH, hydrogen peroxide, metal chelating and nitric oxide radical methods and compared with the known antioxidant ascorbic acid. Further, the anticancer properties of synthesized azo dyes were carried out against breast cancer (MCF-7) cell lines by MTT assay and results revealed that the synthesized compounds exhibited good anticancer property in micro-molar range. Addnl., the anti-inflammatory activities of target compounds were also investigated by protein denaturation method and were found to have effective anti-inflammatory property. In order to predict the binding modes and binding affinity of synthesized compounds, they were docked into the active sites of protein B-cell lymphoma-extra-large (Bcl-xL) to predict their anticancer property. The synthesized compounds were found to have good affinity for B-cell lymphoma-extra-large (Bcl-xL). A good correlation was found between in-silico docking anal. and in biol. screening of all synthesized azo dyes with less binding energies and higher inhibition constants value against the target protein.

Benzothiazole derivatives are essential intermediates in synthesizing a wide variety of medical and pharmaceutical compounds, and there is a great demand for a simple and efficient method to synthesize benzothiazoles under mild reaction conditions. Organic electrosynthesis as an energy-efficient process represents an environmentally benign and safer method than traditional methods for organic synthesis. Herein, authors present bromine-free and straightforward synthesis of 2-amino benzothiazole derivatives via the reaction of aniline derivatives and ammonium thiocyanate using electrosynthesis in the presence of sodium bromide both as an electrolyte and as a brominating agent at room temperature in iso-Pr alc. (i-PrOH) as a solvent. The reaction of ammonium thiocyanate via C-H thiolation routes, using various aniline derivatives, resulted in a simple, green, and bromine-free synthesis of 2-amino benzothiazole in moderate to good yields under mild reaction conditions. Riluzole drug can be produced using the same procedure in moderate yields.

The author of 《Synthesis, structure and reactivity with phosphines of Hg(II) ortho-cyano-aminothiophenolate complexes formed via C-S bond cleavage and dehydrogenation of 2-aminobenzothiazoles》 were Al-Jibori, Subhi A.; Irzoqi, Ahmed A.; Al-Janabi, Ahmed S. M.; Al-Nassiry, Amenah I. A.; Basak-Modi, Sucharita; Ghosh, Shishir; Wagner, Christoph; Hogarth, Graeme. And the article was published in Dalton Transactions in 2022. Synthetic Route of C7H5ClN2S The author mentioned the following in the article:

Addition of 2-aminobenzothiazole (abt) and substituted derivatives to Hg(OAc)2 leads to the high yield formation of ortho-cyano-aminothiophenolate (ocap) complexes [Hg{SC6H3XN(CN)}]n (X = H, Me, Cl, Br, NO2) resulting from dehydrogenation and C-S bond cleavage. The reaction appears to be unique to Hg(OAc)2 and with HgCl2 the product [HgCl2(abt)]n contains an intact abt ligand, but reacts with acetate to afford the ocap complex [Hg{SC6H4N(CN)}]n. Binding of abt to Hg(II) was previously probed in mol. structures of [Hg(sac)2(abt)L] (L = MeOH, DMSO) and these were reexamined to understand the perturbation of abt upon coordination. When the reaction of abt and Hg(OAc)2 was carried out at low temperatures the intermediate [Hg(κ2-OAc)(EtOH)(μ-HNCNSC6H4)]2 was isolated resulting from a single ligand deprotonation thus allowing a mechanism for ring-opening to be proposed. Reactions of [Hg{SC6H3XN(CN)}]n with mono- and bidentate phosphines were studied, affording a series of complexes in which the ocap ligands adopt four different binding modes in the solid state, as shown by a number of crystallog. studies. In all, the ligand chelates to a single mercury center but spans to the second via either: (i) a simple S,N-chelate, (ii) coordination through nitrogen of the CN group, (iii) the sulfur acting as a thiolate-bridge, (iv) both thiolate bridging and cyanide coordination. With PPh3 two different binding modes are seen in complexes [Hg{SC6H3XN(CN)}(PPh3)]2 being dependant upon the nature of the arene-substituent, while addition of excess PPh3 affords mononuclear [Hg{SC6H3XN(CN)}(PPh3)2]. With dppm, binuclear [Hg{SC6H3XN(CN)}(κ1-dppm)]2 result in which the diphosphine binds in a monodentate fashion. With the more flexible diphosphines, dppe and dppb, coordination polymers [Hg{SC6H3XN(CN)}(κ1,κ1-diphosphine)]n result in which ocap binds in a simple chelate fashion. Somewhat unexpectedly, with dppp, binuclear complexes [Hg2{SC6H3XN(CN)}2(μ,κ1,κ1-dppp)] result in which two diphosphines bridge the Hg2 center, while with dppf mononuclear chelates are proposed to result. Thus, the simple and high-yielding ring-opening of 2-aminobenzothiazole and substituted derivatives by mercuric acetate provides ready access to a range of novel ortho-cyano-aminothiophenolate complexes, being shown to be a highly versatile ligand that can adopt a number of different coordination modes.

de Oliveira Lima Filho, Edson; Malvestiti, Ivani published their research in ACS Omega on December 29 ,2020. The article was titled 《Mechanochemical Thiocyanation of Aryl Compounds via C-H Functionalization》.Synthetic Route of C7H5ClN2S The article contains the following contents:

Aryl thiocyanate compounds are important building blocks for the synthesis of bioactive compounds and intermediates for several functional groups. Reported thiocyanation reactions via C-H functionalization have limited substrate scope and low RME. The ball-milling method reported here uses ammonium persulfate and ammonium thiocyanate as reagents and silica as a grinding auxiliary. It afforded aryl thiocyanates with moderate to excellent yields for a wide variety of aryl compounds (36 examples, 8-96% yield), such as anilines, phenols, anisoles, thioanisole, and indole, thus tolerating substrates with sensitive functional groups. New products such as benzo[d][1,3]oxathiol-2-ones were obtained with C-4 substituted phenols. Thus, to our knowledge, we report, for the first time, aryl thiocyanation reaction by ball-milling at room temperature and solvent-free conditions, with short reaction times and no workup. Anal. of several mass-based green metrics indicates that it is an efficient greener method.6-Chlorobenzothiazol-2-ylamine(cas: 95-24-9Synthetic Route of C7H5ClN2S) was used in this study.

And the article was published in Annals of Translational Medicine in 2021. Synthetic Route of C7H5ClN2S The author mentioned the following in the article:

Cancer stemness contributes to hepatocellular carcinoma (HCC) initiation, metastasis, drug resistance, and recurrence. The spindle and kinetochore-associated (SKA) complex has been shown to be involved in tumor progression; however, its effects on cancer stem cell-like properties have not yet been examined This research sought to study each subunit of the SKA complex in HCC systematically. Bioinformatic analyses were carried out to examine the expression and clin. data of the SKA complex′s each subunit in HCC. The expression of the target genes was detected by quant. reverse transcription-polymerase chain reaction and Western blot assays. Clone formation and Transwell assays were performed to assess the proliferation and migration abilities of the SKA complex′s each subunit. Sphere formation assays and s.c. xenograft experiments were performed to investigate the effects of SKA complex subunit 3 (SKA3) on the self-renewal and tumorigenic abilities of HCC. Each subunit of the SKA complex was highly expressed in HCC, but only SKA complex subunit 1 (SKA1) and SKA3 were associated with the poor overall survival of HCC patients. Addnl., the HCC cells overexpressing SKA3 exhibited increased migration, invasion, proliferation, self-renewal, Sorafenib resistance and tumorigenic abilities. Notch signaling played a vital role in the process by which SKA3 promoted HCC stemness. SKA3 promotes HCC stem cell-like properties via the Notch signaling pathway. As SKA3 appears to act as a regulator of stemness in HCC, it might be a potential mol. target for HCC.
